Imagery Rehearsal Treatment (IRT) has received increased attention in the past decade for use with chronic nightmares. Studies suggest that the treatment is promising for the reduction of frequency and intensity of chronic nightmares in trauma exposed persons and may have a generalized impact on symptoms of posttraumatic stress disorder and depression and quality/quantity of sleep, although there is mixed evidence for sleep improvement among veterans. The principal investigator has completed two randomized controlled trials of a modified version of IRT, Exposure, Rescripting, and Relaxation Treatment (ERRT) and is currently conducting a third randomized controlled trial (Davis, 2008; Davis & Wright, 2007). The current randomized controlled trial is comparing ERRT to an active treatment (relaxation). Results demonstrated positive treatment response. Although these trials have included some veteran participants, veterans have not been studied as a group using this protocol. The purpose of this prospective study is to conduct a pre- and post-treatment comparison of suicidal ideation and posttraumatic, depressive, and health symptoms in a single group of veterans.
